Quantum Entropic Cosmology Visual and Technical Engagement Companion

A companion document for the Quantum Entropic Cosmology (QEC) corpus, designed for direct engagement with the theory — to understand what it claims, examine the evidence, find the holes, and assess whether the open problems are worth working on. QEC is a scalar field theory of galactic kinematics that grew into a candidate framework for thermodynamics, gravity, and the Standard Model gauge structure. The empirical core — 82 independent tests across ~900,000 galaxies in SDSS, MaNGA DR17, and DESI DR1 — is documented in QEC1 and QEC2. The theoretical superstructure is developed in the companion theory, thermodynamics, gravity, and Standard Model papers. This document is organized in three parts. Part I presents the empirical case: eight figures from QEC1 and QEC2 explained in plain English. Part II maps the theoretical structure: what is derived from the Lagrangian, what is a motivated conjecture, and what is an open calculation explicitly labeled as such. Part III provides a reading guide: corpus map, reading paths by background, and the specific open problems with their current status. Intended for physicists and mathematicians who want to engage with the work directly rather than wait for journal publication.
